Behavioural evidence suggests that targeting just 20 neurons prompted animals to ‘see’ an image.
In new research, scientists used light to precisely activate cells in a
mouse's visual cortex, re-creating the brain activity involved in
seeing specific patterns.
That observation might help explain why
disordered states—hallucinations, unwanted thoughts, and harmful
actions—arise so readily in the brain. And single-neuron optogenetics
may someday point researchers toward highly targeted ways of stamping out these states and treating symptoms of brain diseases.
"Imagine every neuron in the brain like a key on the piano, You can literally choose which neurons to turn on."
“We don’t know how many cells it might take to trigger a more elaborate thought, sensory experience, or emotion in a person,” says Karl Deisseroth, a neuroscientist and psychiatrist at Stanford College in Palo Alto, California, who led one of many new research, revealed on-line this week in Science, “but it’s likely to be a surprisingly small number, given what we’re seeing in the mouse.”
